(en)BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cosmeticizing pen, and more particularly to a cosmeticizing pen that contains two different cosmetics in two opposite ends thereof.
2. Description of Related Art
A conventional cosmeticizing pen in accordance with the prior art shown in FIGS. 6 and 7 comprises a shank ( 70 ) having a through hole ( 71 ) longitudinally centrally defined in the shank ( 70 ) for containing the cosmetic. The through hole ( 71 ) has a polygonal section ( 72 ) formed on a middle portion of the hollow shank ( 70 ) and an annular groove ( 73 ) defined in an inner periphery of the through hole ( 71 ) near a rear end of the hollow shank ( 70 ). A guider ( 74 ) is longitudinally attached to a front end of the hollow shank ( 70 ) for guiding the cosmetic squeezed out of the shank ( 70 ). A cap ( 75 ) covers the guider ( 74 ) and is attached to the front end of the hollow shank ( 70 ) for protecting the guider ( 74 ) after use.
An actuated rod ( 76 ) is received in the hollow shank ( 70 ) and a having a threaded outer periphery ( 77 ) formed thereon. The actuated rod ( 76 ) is longitudinally movably received in the hollow shank ( 70 ). A sealant ( 78 ) abuts the inner periphery of the polygonal section ( 72 ) to form an airtight effect between the actuated rod ( 70 ) and the inner periphery of the polygonal section ( 72 ).
A rotor ( 80 ) is rotatably mounted to the rear end of the shank ( 70 ). The rotor ( 80 ) includes a hollow driver ( 81 ) formed on one end thereof and rotatably received in the through hole ( 71 ) in the shank ( 70 ). The driver ( 81 ) has a threaded hole ( 82 ) centrally defined therein and the actuated rod ( 76 ) is partially screwed into the threaded hole ( 82 ) due to the threaded outer periphery ( 77 ) thereof. A flange ( 83 ) outwardly radially extends from the protrusion ( 81 ) and rotatably received in the annular groove ( 73 ) when the rotor ( 80 ) is longitudinally mounted to the rear end of the shank ( 70 ).

The first holder ( 55 ) has a teethed periphery engaged to the fifth series of teeth ( 32 ) of the first shank ( 30 ). A first recess ( 550 ) is defined in one side of the first holder ( 55 ) and faces the first pusher ( 57 ). The first holder ( 55 ) has a series of ratchet formed on a periphery of the first recess ( 550 ) and engaged to the first ratchet ( 571 ) of the first pusher ( 57 ) to make first pusher ( 57 ) only be rotated in one direction relative to the first holder ( 55 ). The first holder ( 55 ) has two first guiders ( 56 ) inwardly extending therefrom and each movably received in a corresponding one of the two first slits ( 54 ) of the first actuated rod ( 51 ) such that the first holder ( 55 ) only linearly moved relative to the first actuated rod ( 51 ).
A second drive device ( 60 ) is mounted in the second shank ( 40 ). The second drive device ( 60 ) includes a second actuated rod ( 61 ) having a threaded outer periphery. The second actuated rod ( 61 ) is screwed into the second threaded section ( 26 ) of the guider ( 20 ), extends the guider ( 20 ) and partially received in the through hole ( 52 ) in the first actuated rod ( 51 ). The second actuated rod ( 61 ) has two second slits ( 63 ) defined in the outer periphery thereof and diametrically corresponding to each other.
A second pusher ( 66 ) is sleeved on the second actuated rod ( 61 ) and partially received in the second groove ( 25 ) in the guider ( 20 ). The second pusher ( 66 ) includes multiple second protrusions ( 660 ) outwardly extending therefrom and engaged to a periphery of the second groove ( 25 ) to prevent the second pusher ( 66 ) from rotating relative to the guider ( 20 ). The second pusher ( 66 ) has one side opposite to the guider ( 20 ) and having a second ring of ratchet ( 661 ) formed on the second pusher ( 66 ). A second piston ( 62 ) is mounted on one end of the second actuated rod ( 61 ) opposite to the second pusher ( 66 ).
A second holder ( 64 ) is sleeved on the second actuated rod ( 61 ) between the second pusher ( 66 ) and the second piston ( 62 ). The second holder ( 64 ) has a teethed periphery engaged to the sixth series of teeth ( 42 ) of the second shank ( 40 ). A second recess ( 640 ) is defined in one side of the second holder ( 64 ) and faces the second pusher ( 66 ). The second holder ( 64 ) has a series of ratchet formed on a periphery of the second recess ( 640 ) and engaged to the second ring of ratchet ( 661 ) of the second pusher ( 66 ) to make second pusher ( 66 ) only be rotated in one direction relative to the second holder ( 64 ). The second holder ( 64 ) has two second guiders ( 65 ) inwardly extending therefrom and each movably received in a corresponding one of the two second slits ( 63 ) of the second actuated rod ( 61 ) such that the second holder ( 64 ) only linearly moved relative to the second actuated rod ( 61 ).
With reference to FIGS. 3-5 , when operating the cosmeticizing pen in accordance with the present invention, for example, when using the first head ( 34 ), the sleeve ( 10 ) is moved toward the second shank ( 40 ) to make the first series of teeth ( 11 ) of the sleeve ( 10 ) engaged to the fourth series of teeth ( 41 ) of the seconds shank ( 40 ), and then second shank ( 40 ), the guider ( 20 ) and the sleeve ( 10 ) are longitudinally connected to one another and can not be rotated relative to one another. When rotating the first shank ( 30 ), the fifth series of teeth ( 32 ) of the first shank ( 30 ) drives first holder ( 55 ) of the first drive device ( 50 ) and the two first guiders ( 56 ) of the first holder ( 55 ) rotate the first actuated rod ( 51 ). As a result, the first holder ( 55 ) is rotated relative to the first pusher ( 57 ) in one direction and the first actuated rod ( 51 ) is screwed into the first threaded section ( 23 ) of the through hole ( 22 ) in the guider ( 20 ). The first actuated rod ( 51 ) extends to drive the first piston ( 53 ) moved toward the first head for squeezing the cosmetic that is contained in the fist shank ( 30 ) because the guider ( 20 ) is limited and not rotated.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
